A well advanced time keeping device Quartz watches has burst into scene as the new high-tech gadget 1970s. Inventing a quartz wristwatch was a task of miniaturization, requiring low-power, low voltage integrated circuits, miniature quartz crystal oscillators, small batteries, micro motors, and electronic displays. Quartz watch is time piece that uses an electronic oscillator which is made up with a crystal to keep accuracy in time.

Quartz watch yields incredible accuracy. As the day progress there have been dramatic changes in the design, prices and functions of quartz watches as the first watch Seiko 35 SQ Astron entered into the scene. Quartz watch is far superior to encounter the traditional time pieces. Quartz watches derive their name from the tiny sliver of quartz which divides time into equal segments.

Modern quartz watch has LCD display or traditional mechanical movement with hour and minute hands. Quartz timepieces use the nature of the quartz crystal to provide a very accurate resonator which gives a constant electronic signal for timekeeping purposes. Quartz crystals are piezoelectric, which means that they generate an electrical charge when mechanical pressure is applied to them. They also vibrate if an electrical charge is applied to them. The frequency of this vibration is a function of the cut and shape of the crystal. Quartz crystals can be cut at a consistent size and shape to vibrate at thousands of times per second, making those extremely stable resonators for keeping very accurate time.

Quartz watch has the further advantage that it does not change size as temperature changes. So a quartz plate's size will not change that much with the temperature. Mean while the resonant frequency plate, will not change much, either. It means a quartz watch will be relatively accurate as the temperature changes.

Quartz watch a good time pieces is portable also have its challenges for ever. A low-frequency bar or tuning-fork-shaped crystal is used by modern quartz watches. These crystals are often made from thin sheets of quartz. The quartz sheets are plated like an integrated circuit board and are chemically etched to shape.

The advantage of quartz watches is their simplicity and accuracy - crystals maintain their frequency over broad operating conditions and are cheap to make. The electronics function in a quartz watch initially amplify noise at the crystal frequency. This noise builds up or regenerates into oscillation and the crystal starts ringing. The crystal is formed to have a natural oscillation at around 32,000Hz. These oscillations generate small electrical signals which are 'divided down' by the circuit within the watch to the required frequency (usually seconds) and translated into pulses which are sent to the watch display or a motor to move the seconds hand.

The battery replaced the mainspring as the energy source in the quartz watch. Solar powered watches use the available light. Some of these Quartz watches work on kinetic power. The weight turns a generator that provides the watch with power. One of the product of Quartz watches, particularly Citizen Eco Drive Thermo receives the best source of power is from wearer’s arm and the environment.
